CHRISTOPH MAYER, OF BUTLER, NEWV JERSEY.

MACHINE FOR CLEANING REFUSE RUBBER.

SPECIFICATION forming part of Letters Patent No. 409,693, dated August 27, 1889 Application filed August 12, 1886. Serial No. 210,757. (No model.)

To all whom it may concern:

Be it known that I, CHEIsToPH MAYER, a resident of Butler,- in the county of Morris and State of New Jersey, have invented certain new and useful Improvements in Machines for Cleaning Refuse Rubber; andldo hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to an improvement in machines for cleaning waste rubber and other materials, to fit the same for use and render them salable and capable of being reworked into useful articles; and it consists in the peculiar construction and combination of de vices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is an elevation of the machine. Fig. 2 is a plan Fig. 3 is a front View of the same. Fig. 4 is a longitudinal section taken 011 the line y y of Fig. 2. Fig. 5 is a vertical transverse section taken on line x 00 of Fig. 1.

a represents a frame-work of wood or other suitable material, consisting of two sides firmly secured together by end braces.

Located 011 the upper side or cover at one end of the machine A is a conical hopper or feeding-box a, beneath which and under the cover at a suitable distance is a shaking trough c, resting upon a ledge or projection 011 each side of the frame a and havin at its free end an arm 6 extending outward, resting upon and in connection with cam e, secured to the shaft D The end of the trough c opposite to the cam is supported by a cord or chain 6 attached to and partly wound upon a drum E, located 011 the shaft E Said shaft is journaled in suitable brackets E On its outer end the shaft E has a ratchet-wheel E and hand-wheel E. A pawl E engages the ratchet-wheel. Below the shaking trough e, at a suitable distance, is placed a wire sieve "m, of a requisite-sized mesh, located in a rectangular frame, one end of which is open for the delivery of material and the other end is provided with an arm m, extending outward and engaging a cam misecured to the shaft m To the frame of the sieve m is fastened one end of a spiral spring m, the other end of which is fastened to the cross-bar m, which is a part of the main frame a.

At the end of the machine, and located in a suitable position, is a hopper or duct a of such a form that it will receive the material cast off or rejected by the sieve and conduct it out of the machine to the floor. Below the sieve m is a trough or box g, closed at one end and bottom and having inclined sides with their upper edges wider apart than the width of the sieve m.

v In the lower portion of the box or trough is an Archim edean screw or worm g,provided with suitable conveying-blades. of the screw is supported by suitable bearings anddriven. by a pulley 9 which is driven by a pulley g located 011 the driving-shaft m The inner end of the screw is located in a box N, the lower part of which is provided withand driven by the pulley R. On the side of the trunk N is an opening or ventilator f, provided with a shutter or door f and operated by the leader f I11 the front of the trunk N a sliding plate f is inserted in a suitable orifice formed in the front casing of the trunk N and provided with a handle J. In the lower part of the trunk N is a mouth or opening 70, to permit the entrance of air and the exit of accumulated dust.

The front of the trunk N is provided with an opening a some distance below the ventilating fan or blower R. Above the inclined trunk N is located ahorizontal trunk N, which leads from the machine A to a chamber B, formed for the purpose of receiving the cleansed material. Located at 1) within the trunk N are rollers b 19 secured to suitable shafts seated in proper bearings and driven by the pulleys P D. The rollers b b carry an endless belt or apron b, which travels in an opposite di- I00 rection to the current of air created by the fan or blower R.

The shaft 65 From the 75 I will now describe the process of cleaning and the operation of my newly-invented machine.

Refuse, waste particles of rubber, or other materials intended to be cleaned, are fed into the hopper a, and, falling upon the shakingtrough e, are fed in an even and regular manner upon the sieve m, the amount or rapidity of the feed being determined by inclining the trough to any requisite pitch, which may be done by raising the closed end by means of the cord 6 operated by the handwheel E.

It will be understood that the cam e and arm 6 serve to agitate the trough. The sieve m rejects the coarser particles, and they are passed out of the machine through the duct or tube a. The finer particles pass through the meshes of the sieve m and fall into the box g, the inclined sides of which cause the material in process of cleansing to come into contact with the Archimedean screw or worm g, the blades of which convey the material to the scrubbing-plate H and under the rotary brush H. The particles and impurities are separated and cleaned from dust by the action of the brush H and plate H, and are withdrawn by the action of the rotary exhausting fan or blower R and carried upward through the vertical trunk N and the horizontal trunk N into the chamber B through the orifice or opening I).

The ventilators f and slide f are adjusted by the handles f f to limit the current of air in velocity and in order to allow the dirt or heavier particles to fall upon an endless apron or conveyer d, and which heavy particles are returned to the inclined trough or duct N, pass down the inclined side, and slide through the orifice at out of the machine A into a suitable receptacle. The requisite speed of the machine is regulated by a cone speed-pulley D, having a number of surfaces of different diameters, in the usual manner, and the requisite degree of cleansing by the size of the mesh of the sieve m, speed of rotary brush H, velocity of fan or blower R, and the due adjustment of the ventilators f f What I claim is 1. The combination of the frame a, hopper a, shaking trough e, having arm 6 cam 6 and shaft D duct (i cord or chain e drum E, shaft E pawl E wheel E and hand-wheel E, substantially as described.

2. The combination of the frame a with the trough g, screw g, rotary brush H, scrubbing-plate H, fan R, trunks N N, and endless belt or conveyor d, substantially as specified.

3. The trough g, the plate H, and revolvin g brush H, in combination with the inclined trunk N, communicating with trough g, the fan or blower, the horizontal trunk N, and the endless carrierin the lower side of said trunk, substantially as described.

4. The trough g, the plate H, the revolving brush H, in contact with said plate, and the screw to feed material to said plate and brush, all in combination, substantially as described.

5. The combination, in an apparatus for cleaning waste rubber, of the plate and revolving brush, the screw to feed material to said plate and brush, and the fan or blower, substantially as described.

6. The trough g, having plate H, and revolving brush H, in combination with the inclined trunk N, communicating with trough g, and having the mouth 70, the slide f and the fan or blower, substantially as described.
